1-2-3. Calculation of energy storage filter inductance of tandem Switching Power SupplyFrom the above analysis, we can see that the output voltage of the tandem switch power supply is related to the duty cycle D of the control switch and the energy storage inductance L, because the energy storage inductance L determines the current rise rate (DI/dt), that is, the output current size. Therefore, it is import

1. DSP6000 power-on sequence Problems DSP is indeed a freak. Two common problems are: (1) unable to connect to the CCS development environment; (2) burning chips. I am using TMS320C6713 now. The following experiences are based on DSP6000. Other series may be different. It seems that the performance of the chip has changed, and the chip has never been burned. However, CCS still often cannot be connected. Some of the reasons are related to the stability

Power View is a tool that enables you to create dynamic, interactive reports, and supports a rich variety of chart types, and reports created in power view can be easily shared and used by users who view reports to interact with the Power View report. Starting with this one, Anna will make a dynamic report in power vie

1. Fast power is the n power of fast calculation base. Its time complexity is O (log₂n), and the Simplicity of O (N) compared to the efficiency has been greatly improved. Usage: Used to solve the B-side of a, and B is a very large number, and the complexity of O (n) times out. Then we need this algorithm, note that it can not only be the logarithm of the

1, the hard disk appears bad track. Bad power is easy to cause the hard drive to appear false bad, this kind of fault can be repaired by software generally. In such cases, first check the power supply. If the problem is confirmed to be a power supply, the new power supply with reliable quality and stability should be r
